R Documentation

Prints Logic Regression Formula

Description

Prints formulas for objects fitted by logreg.

Usage

## S3 method for class 'logregtree'
print(x, nms, notnms, pstyle, ...)

Arguments

`x`	object of class `logregtree`, typically a part of an object of class `logreg`, which is the result of the function `logreg`, or a matrix with five columns (see `logregtree`).
`nms`	names of variables. If `nms` is provided variable names will be printed, otherwise indices will be used.
`notnms`	names of complements of the variables. If `notnms` is not provided “not” will be added before the variable names.
`pstyle`	parenthesis style. If `pstyle = 1` (the default) rules are more compact than if `pstyle = 2`.
`...`	other options are ignored

Value

A text representation of the tree will be printed.
